How do I setup a reverse hostname?
When I send an email (using sendmail) from the command line to my email account I get this in the response:
450 4.7.1 Client host rejected: cannot find your reverse hostname,

The reverse hostname is the droplet name. So if you name your droplet something.mydomain.com you get a PTR record of something.mydomain.com
If you already created your droplet simply rename it in the control panel under settings.
your sendmail config should also use this same name.

Does it make a difference that I’m not using Digital Ocean’s name servers? Currently I’m using Hover’s name servers.

No, doesn’t matter reverse ip dns is handled by DO. You can leave your nameservers set at Hover.

Where in sendmail config do you mean?
I can email successfully to my Gmail address, but my Hover address rejects it.
Also if I type my Droplet’s IP address into this tool it says that no PTR record exists.

Can’t really advise you on sendmail. I haven’t touched a sendmail setup since 2003.
It may take a few hours for the name change to propagate out.
I would just hold off until reverse dns resloves.
